RT-PCR confirms microarray data for genes regulated by TSA. Genes found to be differentially expressed based on the array data were tested by semi-quantitative RT-PCR. RNA from log phase E. histolytica 200:NIH trophozoites exposed to 150 nM TSA for 16 hours was used to generate cDNA for the analysis. (A) Genes identified by the array analysis as upregulated in TSA treated parasites (135.m00113, 14.m00410, 337.m00049, 340.m00050 and 146.m00117) are shown. (B) Genes identified as downregulated in TSA parasites (1.m00712, 223.m00071, 223.m00075, and 77.m00173) are shown. (C) Genes identified as being unchanged in TSA treated parasites (247.m00075 and 7.m00480, 13.m00291) and small subunit ribosomal RNA (X61116) were used as a loading control. For all genes, the trends indicated by the array data were recapitulated by the RT-PCR analysis. For all samples, a control reaction without reverse transcriptase control was performed, and was negative.
